Application filed January 18, i883. (No model.) i

` to be applied to the meeting-rails of the sashes.

Its object' is to provide a cheap, simple, easily-operated, andvefficient locking device and it consists inV the matters hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of afastening constructed as proposed by my invention. Fig. 2 is a plan viewot' the same. Fig. 3is a detail of the end Fig. 4t isa fragmentary viewofa modified form of the device shown in Figs. 1 and 2. Fig. 6 is anelevation ofthe stud, and a sectional view .of the end of thelocking-lever shown in Fig. 5. Fig. 7 is a perspective view of the studand its supporting-plate shown in Fig. 5. Fig.v8 is a modified form ofthe stud and plate shown in Fig. 5. 4

A and B are portions ofthe upper andlower sash, respectively, of awindow as ordinarily constructed, and A and B the meeting-railsv of thetwo sashes.

'G is a bent lever, which is pivoted upon the upper or horizontalsurface of the meetingrail B ofthe lowersash by means of a stud orscrew, c. The lever C consists of two arms, C and G2, which arepreferably placedat right angles to each other, and intersect at or nearthe pivotal point of said lever'. Upon the extremity of the arm C',which is arranged lon gitudinally in reference to the rail B', is a knobor handle, c', by which said arm may be grasped in operating the lever.The arm C terminates at or near the face of the vertical side piece, A2,of 'the' upper sash, and has an upturned end, c2, constructed to engagea screw-stud, D, on the said sash inthe manner hereinafter described.The lever C is prefera- 'bly constructed of spring sheet metal, and issupported a short distance above the upper surface of the rail B' bymeans of a plate, E, through one end ot' which the pivot-screwc passes,and which will be hereinafter more fully described. The end of the armC'Z projects beyond the plate E, so that it is unsupported from beneath,and is capable of slight vertical movement on account ofthe exibility4of the sheet metal of which the lever C is composed, and said arm has anupturned end, c2, which is provided with an incline, c3, and asemicircular notch, c4, constructed to engage the stud D. The end c2 andthe notch c4 therein are shown more plainlyin Fig. 3,which is asectional view of said end. rlhe notch c4 is brought into engagementwith the stud I) by a lateral movement of the end of the arm C, giventoit by moving. the end of the arm C'. In this operation the end of thearm C is forced downwardly by the contact of the incline c3 with thestud until the. said stud has passed over the incline and into the saidnotch.- By' making' the arm C2 iiexible, as described, and forming theincline c3 onthe upturned end thereof, a slight variation in therelative positions of the upper and lower sashes 'will not aiect the,operation of the de- 4 vice; but the yielding of the said arm downwardwill allow it to engage the stud, notwithstanding such variation. Thesaid springarm G2 also tends to force the upper andlower sash inopposite directions by its upward pressure on the stud when the deviceis locked, and thus tends to keep the window tightly closed. Thedownward movement of the arm C2 is limited by the upper surface of therail B beneath it, so that if an attempt is made to raise the sash saidspring will yield slightly until it strikes said rail, and a positivelock will then be formed bythe contact of said arm therewith. The end ofthe lever C2 is disengaged from the stud D by drawing the end ot the armC outward, the notch c4 becoming disengaged by the. yielding of the endof the arm C2, as before described.

The stud D is preferably provided with an enlarged head, d, and theupturned end c2 ot' the arm C2 is inclined, as shown in Fig. 2, so thatthe head el willcome in contact with the inclined face of the upturnedend, in the oper- IOO ation ot'locking, and draw the meeting-rails A andB' together for the purpose of making a tightjoint between saidmeeting-rails.

One of the locking devices described is preferably placed on each sideof the window, so that when it is locked the meeting-rails will be drawntogether equally at both ends aud a tightjoint made between themthroughout their entire length. The plate E, upon which the lever G ismounted, extends from'the pivotal point of said leverlongitudinallybeneath and to the end of the arm C', and has a curved projection, E',corresponding with the circular path of the end ot' said arm. Upon theunder side ot' the arm C is a short downwardly-proiecting pin, c",preferably placed beheath the knob c', and in the plate E, at the twoextremities of the movement of said arm, are formed depressions c c,adapted to receive said pin for the purpose oflocking the'arm C ateither limit ot' its movement. Thepin @is of' such length that itremains normally in the depression c', but may be removed therefrom byraising the end of the arm C', which is sufficiently flexible for thispurpose.

The end of the arm C is, by the device described, prevented frombeingmoved accidentally when the fastening` is unlocked, andadditionalsecurity is given to the fastening thereby when locked, thelever G being held in position both by the pin c5 in the depression cand by the engagement ot the notch c4 withthe stud D.

' ln Figs. l and 2 the stud D is shown as projecting from the face ot'the vert-ical side piece or rail, A2, ofthe upper sash, and in order toallow said stud to pass the projecting edge ot the meeting-rail B whenthe sashes are moved a notch, b2, is made in the said edge, beneath thesaid stud, as shown in the igures inen- 40; tioned.

ln Figs. 4, 5, 6, and T are shown a modiii Y cation ot' the devicedescribed, in which the stud D is placed in a recess in thepiece A2, sothat the head of the' said stud is flush with the face of the saidpiece, and the notch b2 in the rail B2 is rendered unnecessary. I haveprefably made the stud D iu the form of a projecn tion or lug uponaplate, F, which is placed in a recess formed in the corner of the pieceA2, and secured therein by screws, or in any other desired manner. Suchplate and the projection D thereon are shown more plainly in Figs. G and7. A projecting rim, d', corresponding with the head d ot'the stud D, asshown in the figures lastmentioned, is provided for the purpose ofacting, in connection with the inclined end of the arm C2, to draw thelower portions of the sashes together. Vhen the stud D is placed in arecess, as above described, the end of the lever C2 is arranged toproject beyond the inner edge of the rail B when the device is locked,in order 'to enter said recess, as shown in Fig. v5, and said lever C2is given sufficient movement so that when disengaged from the stud D itsends will not project beyond the rea-r edge of the raill B', as shown bydotted lines, which indicate the changed position ofthe lever C in Asaidligure. It is not essential that the lever C should be bent as shown,but it may be straight, the plate E in such case be ing placed in thesame position relative to the arm C, as has been before described inconnection with the bent lever shown.

In Fig. S is shown a modified form ot' the plate F and stud D, inwhichthe said plate is secured to the upper sash by a screw, (indicatedin the figure mentioned by d,) which is provided with a thimble, d2,between its head and the plate F, in order to hold said plate inposition. Instead of using the thimble d2 upon the screw d', asshown,the screw may have an enlarged portion adjacent to its head, whichwill form a shoulder to press upon the plate F and retain it in positionon the sash.

The stud D, instead ot' being attached to the vertical side piece of theupper sash, as shown, may be placed upon or form part of a standard orbracket attached to the top of the meeting-rail A ot' said sash, and insuch case said standard or bracket, with the stud thereon, and thepivoted lever C can be placed at the center ofthe meeting-rails, thusforming a single central fastening, which can be used instead ot' alocking device at eachside ofthe window.

One or more additional studs, D', as shown in Fig. l, may be placed uponthe upper sash,

each of which is arranged to engage the lever" C in the manner beforedescribed, so that the sashes may be locked together in any one of theseveral positions. Then constructed to lool: in several positionsthe/stud D is preferably placed in a recess in the upper sash, and theplate F, which has been described as being used in connection with saidstud, is provided with a lower flange, F2, as shown in Fig. S, whichacts against the lower side of the end ofthe arm G2, and, in connectionwith the stud, prevents any movement of the upper sash in eitherdirection when theyrare locked together in the manner described.

The notch c4 in the end of the spring-arm O2 is not essential to theoperation of the device described, and the upturned end of said arm maybe provided with a simple incline, which will rest againstthe under sideof the stud D when the device is locked, the said arm in such case beingheld in position by the engagement of thevpin c5 on the arm C with thedepression c in the plate E. When the notch is omitted the inclined edgeof the upturned end ot' the arm C2 will act, in conjunction with theflexibility of said arm, both to allow for variationin the positionofthe stud'in closing the window and to press the sashes in oppositedirections, so as to tend to close them tightly, as before described.

I claim as my invention- Il In a sash-fastening, the combination, with astud affixed to the vertical rail of the upper sash, ofapivoted leversupported upon and above the upper surface of the lower sash,and Yhaving an elastic vertically-yielding arm, pro- IOO IIO
